DETACHED HEDDLE' OR THE LIKE.

To alljwiumt itmay. concern Be it known. that I, CHARLEs- E., BLAIR, a.citizen. of the United States, and a resident of Dorchester, county ofSuffolk, State of hilassachusetts, (whosepost-oflice address is 195Freeportstreet, Dorchester, Massachusetts,)- have inventedan'lmprovement in.

Detached. Heddles or the like, of which thev following description, in;connection with the accompanying drawings, is a specification, likecharacters on thev drawings representing like. parts This inventionrelates to independent. or detached heddles, drop wires, or the; like,and more particularly to the construction of said: heddles so'that theymay be assembled in. an; organized series capable of ready selection andseparation either by hand or by mechanical devices.

This application is a division of my prior, copending application SerialNo. 474,885, filed May 8., 1909.

The invention will be best understood by reference to the followingdescription when taken. in connection. with the, accompanyingillustration of one. specific embodiment thereof, while its scope willbe more particularly pointed. out in the appended. claims.

In the drawings: Figure 1 shows anassemblage of detached heddles or dropwires constructed and arrangedin accordance with one form oftheinvention and shown in cooperative relation to mechanical separatingor. releasing devices; Fig. 2 islan elevation of, a metallic heddle ordrop wire. with the.

associated devices shown in cross section; and Figs. 3, land 5 are.diagrammatic viewsillustrating the internal variation in form ofsuccessive heddles and the. relation thereto of the separating orreleasing devices at different stages of their operation.

Referring to the drawings, I have. shown the invention embodied in theform of detached heddles of the kind usually formed of thin,.resilientsheet metal and employed in the loom as: drop heddles, but the inventioncontemplates independent, detached heddles of other. forms ofconstruction and also similar loom elements, such as drop bars or dropwires, the term heddle being used as a generic term to include those.devices as well.

In the specific form of the invention illustrated it will be seen thatthe heddles or Specification of Letters Patent.

drop,- wires are of two different types,1 and Each heddle-isformed witha threading aperture. 3: and an elongated slot at the end, the latterserving as a suspension opening: andi adapted to receivethe suspensionor hanger bar The slots-of the-heddlesl are gllCllCltfiCl at 5 and theslots of the heddles The; upper ends of the slotsasswell as theapertures 3.coincide.in both sets or types of heddles, but the lowerends. of the slots 5 are nearer the aperturesB in the heddles l thanarethe-lowenends of the slots 6 in the heddles 2:, thereby providing longerslots in the; heddles 11' than in. the heddles 2. The heddles 2. are:furthermore provided with the apertures? which are arranged between theaperturesil; and the slots 6. and which coincide. in part with. thelower ends of the slots 5 instheheddles 1 It therefore follows that.when-a1 number of. the heddles of both sets are arranged. in alinement,a substantially continuous aperturethrough the series is.- formed; bythe. apertures] and the lower ends ofthe slots-5 as isshowninFig, 2.

The internalvariationin construction just described however, providesfor. arranging the heddles in. series in alternating order, that istoisay, first. aheddle of one type and then aheddle. of. the; other.type, and. so on, so that. due. to this. regnlar,.alternate variation.of. internal. form heddles; a. holding; portion: is. presented. byeachheddle which isuncovered by the preceding heddle, By thisimeansseparating or releasing. devices may be: employed so that, whenengaging; the holding portion of. the foremost heddle it. will hold.back all. succeeding heddles of the. series, but by being shifted, tothe; holding: portionv of the next succeeding heddle; the first. heddleof the seriesiisa thereby released or separated while the remainingmembers of the. series. are still held. back or retaine The cooperationbetween the. structure of thedescribed forms of heddles and a typicalform of mechanical. releasing device may be illustrated by the. action.of the releasing devices. shown in the drawings. The heddles beingassembled, as indicated in igs. 5v and. 6,-they are initially retainedin series by releasing hook. 8 formed at. one end of a releasing rod.8", the latter extending between. successivev means of a/ retaining and.

through the continuous aperture referred to as formed in the series ofheddles. The

heddles are su 3 )orted n 3011 a su oortin rod 9 which is one member ofa two part telescopic shaft, the supporting rodbeing adapted to fitloosely within the apertures 3 with which the heddles of both sets areprovided, and the rods 8* and 9 being arranged parallel to thesuspension bar 4. a

The slots 5 and apertures 7 are so located with reference to theapertures 3 that the releasing rod 8 is permitted a free movement in thecontinuous aperture thereby provided. By reason of the arrangement andrelation of the aperture 7 and the slots 5, however, the releasing hook8, when eX- tending upwardly, is in a position to engage the holdingportion of a heddle 2 directly above the aperture, but, when extendingdownwardly, is in a position to clear the aperture and engage theholding portion of the next adjacent heddle 1 directly below the slot 5.The result is that when the hook extendsupwardly, it retains theforemost heddle 2 together with'the series behind the vame, whilereleasing the preceding heddle 1 When turned downwardly, it frees or re-.eases the heddle 2, holding back the succeedng heddles l'together withthe series behind he same. In other words, when the hook, vhich, byanalogy, may be compared to the .iour hand of a clock, points totwelve,as

shown by Fig. 1, it is adapted to retain a heddle 2, but when it isturned to approximately siX oclock, it releases the heddle2, retainingthe succeeding heddle 1. It is apparent, therefore, that, if the heddlesare arranged alternately with regard to their structural variation andthe releasing rod 8 with its hook 8 be extended through thesubstantially continuous aperture thereby formed, continued rotation ofthe releasing hook in one and the same direction will effect thereleaseof the heddles one by one at half rotation of the hook, while retainingall the remaining heddles of the series.

Any suitable mechanism may be provided for turning the releasing shaft,or the same nay be turned by hand, as desired, and any lesired means mayalso be employed for maintaining the heddles compacted against thereleasing hook. These and other mechanical featuresrelating to thereleasing devices form no material part of the present invention whichconcerns the arrangement or construction of the heddles themselves.

The separation of the successive heddles as described may be utilizedfor any desired purpose. The heddle after being released, for example,may be conveyed to a position where it is adapated to be acted upon bythreading devices. In the illustrated embodiment of the invention, thereleased heddle is adapted to be fed by gravity or other means along thesupporting rod 9 and to be engaged by the turning and facing screw 10carried by the other member 11 of the telescopic shaft 9 and therebyfaced for the threading operation which may be either automatic ornon-automatic. As these devices form no part of the present invention,

they need not be further described in detail.

.is such that by the method of assembling them or arranging them inseries, as, for eX- ample, by a reversal of the 13031131011 ofsuccessive heddles, a holding portion is presented by each heddleuncovered by an aperture in the preceding heddle.

Ido not herein claim broadly any alternate variation in arrangement orconstruction of the heddles whether internal or ex: ternal, claims tothat generic feature being embodied in my copending application SerialNo. 824, 2 19 filed llLlarch 12,1914.

While for illustrative purposes I have herein shown and described onespecific embodiment of the invention,- it is to be under-- stood thatthe same is not limited to the de tails of form or arrangement hereinshown, but that extensive deviations may be made therefrom withoutdeparting from the spirit thereof.
